Extension to Lua Runtime

We are extending our Lua runtime to support the following Databricks client method:

databricks/client.alter_table(table_name, schema_name, catalog_name, alter_statement)
Usage example:

client.alter_table("my_table", "main", "my_table", "ALTER COLUMN ORG_NAME SET MASK some_catalog.some_schema.pii_mask")
This will generate and execute the following SQL statement:

ALTER TABLE my_catalog.main.my_table
ALTER COLUMN ORG_NAME SET MASK some_catalog.some_schema.pii_mask
see ALTER TABLE reference

Update: we will implement a more general API similar to the databricks sql API
databricks/client.execute_statement(warehouse_id, catalog_name, schema_name, sql_statement)
returns status
